While CISA passed easily, not everyone who voted for the bill saw it as ideal legislation. Earlier in the day, an amendment that would have greatly improved its privacy protections failed by a margin of just two votes, 47-49. Rather than kill the unamended legislation outright, however, dozens of lawmakers decided to vote for it anyway.

The most outspoken group opposing the bill, Fight For the Future, noted in a scathing statement that the vote would be one we one day look back at as being formative for the internet.

"This vote will go down in history as the moment that lawmakers decided not only what sort of Internet our children and our children's children will have, but what sort of world they will live in," the group wrote in an emailed statement. "Every Senator who voted for CISA has voted for a world without freedom of expression, a world without true democracy, a world without basic human rights."

It may not be that simple, but then again, maybe it is. So here's a list of who voted for CISA, who voted against it, and who abstained. Republican presidential candidates Marco Rubio, Ted Cruz, Rand Paul, and Lindsey Graham are all in Denver for Wednesday's debate. Paul is anti-CISA but didn't think it was worth sticking around in Washington for the vote.

The only presidential candidate to vote on the legislation was Bernie Sanders, who voted against it.
